The sheriff's office identified Jessie Nagy, 78, as the suspect, and said he died Thursday of complications from the self-inflicted gunshot wound. He had been charged with first-degree murder and felony firearm, and was listed in stable condition before his death.

Just before 9 p.m. on Aug. 28, the sheriff's office got a 911 call from the son of the couple, in Florida, who said he'd just heard from his father, who was slurring his words.

Police conducted a welfare check at the couple's home on Mackenzie Drive, and found 69-year-old Janet Nagy dead in the master bedroom, having been shot multiple times in her head, legs and hands.

In the master bedroom police also found Jessie Nagy alive, with a gunshot wound to his head. Police said that the home showed no signs of forced entry or theft.
